This study evaluated the longitudinal impact of these processes on organized sport participation and moderate-to-vigorous PA (MVPA) among male and female adolescents. METHODS: This study used secondary analysis of data from a longitudinal cohort of 6639 adolescents (Age = 12.92 ± 0.81 years; Males = 3302; Females …
The Implementation of a Blended In-Person and Online Family-Based Childhood Obesity Management Program
The EIP was highly acceptable and feasible for families and delivery partners, but recruitment, attendance, and online engagement were implementation challenges. Program adjustments are recommended prior to scale-up. These strengths and limitations can help to inform other multi-site childhood healthy living interventions
A web-based physical activity intervention targeting affect regulation
Early career professionals (ECPs) are a critical target for physical activity (PA) promotion. Affect contributes to an established PA intention-behaviour gap and is pertinent among ECPs.Objective The purpose of this study was to examine the feasibility and acceptability of a web-based intervention and explore the effects on secondary outcomes (moderate-to-vigorous PA (MVPA), emotion regulation, multi-process action control constructs).Methods Adu…

Piloting the Virtual PLAYshop Program
The PLAYshop program is a parent-focused physical literacy intervention for early childhood. This single-group mixed-methods pilot study aimed to explore the feasibility of virtually delivering and assessing the PLAYshop program. The virtual PLAYshop program included a virtual workshop, resources/basic equipment, and two booster emails (3-week and 6-week follow-up). Data on 34 preschool-aged children (3-5 years) and their parents from Edmonton an…

The Relationship Between Social Media Data and Crime Rates in the United States
Crime monitoring tools are needed for public health and law enforcement officials to deploy appropriate resources and develop targeted interventions. Social media, such as Twitter, has been shown to be a feasible tool for monitoring and predicting public health events such as disease outbreaks. Social media might also serve as a feasible tool for crime surveillance. In this study, we collected Twitter data between May and December 2012 and crime …
The relationship between social media use and sleep quality among undergraduate students
Insufficient sleep is a growing health problem among University students, especially for freshmen during their first quarter/semester of college. Little research has studied how social media technologies impact sleep quality among college students. This study aims to determine the relationship between social media use and sleep quality among freshman undergraduates during their first quarter in college. Specifically, we explored whether variation…
